So level curves, level curves for the function z equals x squared plus y squared, these are just circles in the xyplane And if we're being careful and if we take the convention that our level curves are evenly spaced in the zplane, then these are going to get closer and closer together, and we'll see in a minute where that's coming fromJan 14, · The family of planes a x b y c z = d define, implicitly, a family of functions z = f (x, y) = 1 c d − a x − b y, for c ≠ 0 To find the level curves of this function, you fix z = k for an arbitrary constant kOliver Knill, Harvard Summer School, 10 Chapter 2 Surfaces and Curves Section 21 Functions, level surfaces, quadrics A function of two variables f(x,y) is usually defined for all points (x,y) in the plane

Surfaces and Contour Plots Part 6 Contour Lines A contour line (also known as a level curve) for a given surface is the curve of intersection of the surface with a horizontal plane, z = cA representative collection of contour lines, projected onto the xyplane, is a contour map or contour plot of the surface In particular, if the surface is the graph of a function of two variables, say zBy combining the level curves f (x, y) = c for equally spaced values of c into one figure, say c = − 1, 0, 1, 2, , in the x y plane, we obtain a contour map of the graph of z = f (x, y) Thus the graph of z = f (x, y) can be visualized in two ways, one as a surface in 3 space, the graph of z = f (x, y),1624 // Summary for how to sketch level curves Whenever you're dealing with a multivariable function, the graph of that function will be a threedimensional figure in space If you take a perfectly horizontal sheet or plane that's parallel to the xyplane, and you use that to slice through your
